Hello all,
A friend of mine is going to play Santa Claus in Lapland next winter and I'm helping him to make a letterbox for the kids to post their Christmas letters. The idea is that a sound clip is played when a letter is inserted. My first idea was to reuse a cheap mp3 player, upload one song on it and connect its play button to a mechanical switch. However, the problem is that on almost all mp3 players, the play button also acts as pause button. That will cause the clip to pause when e.g. a bad (double) contact is made or when a new letter is posted while the clip is still playing.
I also looked around for small electronic kits, found the perfect solution in following kit:

But I faced the same problem as also here the play/pause connector pin is shared.
Now I'm looking for an (electronic) solution to make sure that after a contact is made, no new contact can be made for x seconds. This ensures that the clip finished playing before a contact towards the play/pause button can be made again...
Can anyone help me with this?
Alternative solutions are welcome as well of course!
Thanks for your help!
